Description

Technical Field

[0001] The utility model relates to the technical field of pipeline joints, in particular to an oil pipeline joint in an oilfield. Background Technique

[0002] Petroleum is a viscous, dark brown liquid, known as the "blood of industry". The oil pipeline system, which is used to transport petroleum and petroleum products, mainly consists of oil pipelines, oil transfer stations and other auxiliary related equipment. It is one of the main equipment in the petroleum storage and transportation industry and also the main transportation equipment for crude oil and petroleum products. Pipeline oil transportation has the characteristics of large transportation volume, good airtightness, low cost and high safety factor. In oilfields, pipelines are generally used to transport petroleum.

[0003] When connecting oil pipelines in an oilfield, pipeline joints are needed. At present, some pipeline joints use a simple threaded connection method, and gaps are likely to occur between pipelines, resulting in poor sealing between the two pipelines, and then causing oil leakage, which not only affects the transportation of oil but also causes waste of oil. Therefore, an oil pipeline joint in an oilfield is proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide an oil pipeline joint in an oilfield to solve the problem that gaps are likely to occur between pipelines when the existing pipeline joints use a simple threaded connection method.

[0005] To achieve the above purpose, the utility model provides the following technical solution: An oil pipeline joint in an oilfield includes a joint connecting sleeve. The middle part of the inner side wall of the joint connecting sleeve is fixedly connected with a conical circular seat. The left end of the joint connecting sleeve is inserted with a first pipeline, and the right end of the joint connecting sleeve is inserted with a second pipeline. Two connecting blocks are symmetrically and fixedly connected to the outer side walls of the first pipeline and the second pipeline. Two threaded pipes are symmetrically and fixedly connected to the outer side wall of the joint connecting sleeve. A threaded sleeve is threadedly connected to the outer side wall of the threaded pipe. Connecting rings are fixedly connected to the mutually repulsive sides of the two threaded sleeves. A connecting frame is connected to the outer side wall of the connecting block. One end of the connecting frame away from the connecting block is fixedly connected with a connecting ring. A circular ring chute is arranged on the outer side wall of the connecting ring. Sliders are evenly and slidably connected to the inner side wall of the circular ring chute. The adjacent sides of the sliders and the connecting rings are welded. The two sides of the inner side wall of the conical circular seat are smooth curved surfaces, and two rubber sleeves are symmetrically bonded to the inner side wall of the conical circular seat.

[0006] As a further preference of this technical solution: Two elastic dust-proof sleeves are symmetrically bonded to the inner side wall of the joint connecting sleeve.

[0007] As a further preference of this technical solution: The elastic dust-proof sleeve is made of fluororubber.

[0008] As a further preference of this technical solution: a connecting bolt is threadedly connected between the connecting block and the connecting frame.

[0010] As a further preference of this technical solution: a sponge sleeve is sleeved on the outer side wall of the holding rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, the first pipe and the second pipe are inserted into both ends of the inner part of the joint connecting sleeve, the connecting block and the connecting frame are fixed, the threaded sleeve is rotated to move the threaded sleeve towards the middle of the joint connecting sleeve, the threaded sleeve pulls the connecting ring and the slider, the slider pulls the connecting ring, the connecting frame, the connecting block, the first pipe and the second pipe, so that the first pipe and the second pipe penetrate deep into the inner part of the joint connecting sleeve. Under the action of the pulling force, the first pipe and the second pipe extrude the rubber sleeve, causing the rubber sleeve to deform and fill the gaps between the conical circular seat and the first pipe and the second pipe, increasing the sealing performance, avoiding the occurrence of oil leakage, ensuring the safety of oil transportation, and reducing oil waste.

A connecting frame 9 is connected to the outer side wall of the connecting block 5. One end of the connecting frame 9 away from the connecting block 5 is fixedly connected to a connecting ring 10. An annular chute 11 is formed on the outer side wall of the connecting ring 10. Sliders 12 are evenly and slidably connected to the inner side wall of the annular chute 11. The adjacent sides of the sliders 12 and the connecting rings 8 are welded. The two sides of the inner side wall of the conical circular seat 2 are smooth curved surfaces. Two rubber sleeves 13 are symmetrically adhered to the inner side wall of the conical circular seat 2; insert the first pipeline 3 and the second pipeline 4 into both ends of the inside of the joint connecting sleeve 1, fix the connecting blocks 5 and the connecting frames 9, rotate the threaded sleeve 7 so that the threaded sleeve 7 moves towards the middle of the joint connecting sleeve 1. The threaded sleeve 7 pulls the connecting ring 8 and the slider 12, and the slider 12 pulls the connecting ring 10, the connecting frame 9, the connecting block 5, the first pipeline 3 and the second pipeline 4, so that the first pipeline 3 and the second pipeline 4 penetrate deeper into the inside of the joint connecting sleeve 1.

[0022] In this embodiment, specifically: two elastic dust-proof sleeves 14 are symmetrically adhered to the inner side wall of the joint connecting sleeve 1; during the process of inserting the first pipeline 3 and the second pipeline 4 into the joint connecting sleeve 1, the elastic dust-proof sleeves 14 will be squeezed, and the elastic dust-proof sleeves 14 will deform and fill the gaps between the joint connecting sleeve 1 and the first pipeline 3 and the second pipeline 4, preventing dust and water vapor from entering the inside of the joint connecting sleeve 1 and corroding the rubber sleeve 13.

[0023] In this embodiment, specifically: the material of the elastic dust-proof sleeve 14 is fluororubber; by virtue of the characteristics of fluororubber such as high temperature resistance, oil resistance, and chemical corrosion resistance, the durability of the elastic dust-proof sleeve 14 is improved.

[0024] In this embodiment, specifically: a connecting bolt 15 is threadedly connected between the connecting block 5 and the connecting frame 9; by means of the connecting bolt 15, the connection between the connecting block 5 and the connecting frame 9 can be ensured to be firm, and at the same time, it is convenient for disassembly.

[0025] In this embodiment, specifically: a grip rod 16 is evenly fixedly connected to the outer side wall of the threaded sleeve 7; holding the grip rod 16 is convenient for rotating the threaded sleeve 7.
